DISK CORN-PLANTER.

SPECIFICATION forming part of Letters Patent N o. 448,943, dated March24, 1891.

Application filed December 8, 1890. Serial No. 373,912. (No model.)

T0 all whom, t may concern.-

Be it known that we, CLARENCE ll. DOOLEY and HARRY L. DooLEY, citizensof the United States,residing at Bloomington, in the county of McLeanand State of Illinois, have invented certain new and'useful Improvementsin Disk Corn-Planters; and we do declare the following to'be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertaius to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to certain new and useful improvements in diskcorn-planters, and it has for its objects, among others, to provide animproved device of this character which shall be simple and cheap in itsconstruction, durable, and efficient in use.

Another object of the invention is to dispense with runners and in theirstead employ disk wheels which will cut and lift, and therefore do goodwork in hard ground where a runner or shoe could do practicallynothing,-

making loose earth with which to cover the seed. These wheels will notpack the ground when it is damp, as a wedge-shaped runner will do. XVeprovide the inner ends of the axles with small wheels or bumpers, sothat the inward pressure of the wheels will cause them to roll togethervon their bumpers and thus avoid wear on the wheels and boxes that wouldotherwise follow. The inner side of a disk wheel set at a slight anglewill, under almost any condition of the soil, remain clean, while thereverse is true of the outside. We provide Scrapers on the outside ofeach wheel,which are fastened rigidly to the grainspouts. XVe employsprings bearing on these spouts, the.tendencythereof being to press themaway from the wheels; but the scrapers, being made rigid to them, willnot allow them to be withdrawn. The effect of this is that the Scrapersare made to bear more lor less, as desired, provision being made for thetightening or loosening of the bolt, which will be more fullyhereinafter described. The grain-spouts are so attached to the frame ofthe machine that they admit of lateral movement, but cannot move eitherforward or y mechanism.

back. This lateral movement is to allow the lower point of the spout tobe controlled by the scraper, which, being acted upon by the saidspring, is made to conform to any side movement of the wheel or possibleunevenness of the same. W'e arrange the'lower point of the grain-spoutso that it will extend forward in contact with t-he wheel, but so thatthere will be no pressure against the wheel as the spring bears it, orrather inclincs the spout away, but prevented from too much movement bybeing rigid to the scraper. This arrangement of the lowest point of thegrainspout is considered of great importance, as by this means is formedan unbroken line from wheel to back of spout, allowin gno place to catchand drag rubbish.

Other objects and advantages of the invention will hereinafter appear,andthe novel features thereof will be speci lically defined by theappended claims.

The noveltvin the )resent instance resides The invention is clearlyillustrated in the accompanying drawings, which, with the letters ofreference marked thereon, form a partv of this specification, and iuwhich- Figure l is a bottom plan view of our improved corn-planter, Fig.2 is a side elevation of the seed-spout and the accompanying Fig. 3 is adetail perspective view of the same. Fig. et is an enlarged perspectivedetaillooking at right angles to Fig. 3.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates thefront frame of the machine, to the forward cross-bar of which the tongueB is attached in any suitable manner. To the rear cross-bar of theirframe are attached the seed-boxes c, which may be of any of the approvedforms.

C is the rear framehiuged to the rear crossbar of the forward frame A inany suitable manner. v

, Journaled in vsuitable boxes on the under side of the frame A are thetwo axles D and ICO E, each independent of the other, and to the outerend of each is secured a disk wheel F, the construction of which will bemore fully hereinafter set forth. The inner adjacent ends of theseaxles'are journaled in suitable boxes on the under side of the parallellongitudinal bars e, between which the tongue is secu red. These barsare arranged a sufficient distance apart to permit of the insertionbetween them of the small wheels or bulnpers b, which are attached oneto each axle and arranged to rub against each other, as shown in thedrawings, the adjacent portions being rounded, as shown. These roundedbumpers prevent wear on the boxes and wheels, as will be readilyunderstood. The disk wheels are each composed of a band d., preferablyof steel, about three-sixteenths of an inch in thickness by four incheswide. To this band are fastened the spokes c, which are set in the hubfon the axle. rlhese wheels are set at a slight angle to theperpendicular, so that they will keep clean under almost all conditionsof soil.

Gr are the seedspouts communicating with the seed-boxes in the usualmanner and so attached to the frame A as to allow of slight lateralmovement,but prevented from movement either forward or back. Thisconnection in the drawings is shown as formed by a triangular wire g,which is held in staples or eyes it, so that it may rock somewhatlaterally, but cannot move otherwise.

ll are springs arranged to bear against the seedspouts so as to pressthem away from the wheels, the said springs being connected at one endto the. frame A and provided with an adjusting-bolt t', which passesthrough the spring and into the frame. Turning this bolt or screw in orout regulates the tension of the spring upon the spout.

Attached tothe seed or grain spouts are the Scrapers I, which are madewith a bend or loop j, which embraces the wheel, and the free end of thescraper comes against the outside of the wheel, as clearly shown. Itisgently pressed against the wheel by the action of the spring justdescribed. The pressure of the scraper against the wheel is regulated bythe adjustment of the screw or bolt fi, which moves the spout in or out,and the scraper being rigidly attached to the spout necessarily moveswith it. The lowest point of the spout extends forward, as shown at 7c,and comes in contactI with or bears against the wheel upon the inner1face thereof; but there will be practically no pressure against thewheel, as the spring tends at all times to keep the spout inward. Thisarrangement of the spout with its lowest point in contact with t-hewheel is an essential feature in our device, as we thus form an unbrokenline from the wheel to the back of the spout, thus allowing no place tocatch and drag along rubbish.

J are the covering-hoes, provided at their front ends with a jointadmitting of no lateral movement, but provided with a spring Z, whichexerts a slight downward pressure thereon. These covering-hoes are notdesigned to cutinto the ground, but are designed to be arranged on aplane above that of the lowest periphery ofthe wheels, and thus bringingagain into the furrow the earth lifted out by the wheels.

The lnachine is simple, durable, and in practice has proved most eicientfor the purpose for which it is intended.

Various modiiications in detail may be resorted to without departingfrom the spirit of the invention or sacrificing any ot' its advantages.

That we claim as new is l. The combination, with the frame and the diskwheels, of the spouts arranged to move laterally, the triangular wireconnecting' the spout and frame, and the springs bearing upon thespouts, substantially as and for the purpose specified.

2. The combination, with the frame and the disk wheels, of the spoutsarranged to move laterally, and the springs on the frame and bearing onthe spouts, and provision for adjusting thetension of the springs,substantially as specified.

The combination, with the frame and the disk wheel, of thelaterally-movable spout and the scraper carried thereby and having aloop embracing the wheel, andthe triangular wire g, connecting the spoutand frame, substantially as specified.

et. The combination, with the frame and the disk-wheel, of thelaterally-movable spout having its lowest point in contact with thewheel, the triangular wire secured to the spout and working looselythrough staples on the frame, and the scraper carried by the said spout,substantially as shown and described.

5. The combination, with the frame and the disk-wheel, of the spoutarranged to move laterally, the spring bearing against the spout, thelower extension of the spout bearing against the wheel, and the scrapercarried by the spout and having a loop embracing the wheel,substantially as specified.

In testimony whereof we aiiix ou rsi gnatu res in presence of twowitnesses.
